BACKGROUND

Baking equipment and cookware items are available in a variety of different sizes and dimensions based upon the food being baked. A bread loaf pan is narrower with higher walls to allow proper rising of the baking bread. For example, a typical size of such a bread pan measures 9 inches long by 5 inches wide by 3 inches high. Unlike a bread loaf pan, a cake pan tends to be wider and shorter, due primarily to ensure the ingredients included bake thoroughly and correctly. For example, a typical size of such a cake pan measures 8 inches square by 1.5 inches high. Because of the different sizes and specifications of each cookware item corresponding to the particular food product, a baker who wishes to bake a variety of foods requires several baking pans and tools varying in size.

DETAILED DESCRIPTION

It will be appreciated that different food items require different sized baking receptacles depending upon serving size, ingredient type and baking time and temperature. Acquiring a range of different pans, trays and other cookware items can be quite costly and also burdensome to store and keep conveniently accessible. Having multitude of cookware items and baking equipment on hand requires the dedication of extra storage or cupboard space, as well as significant initial cost and investment to acquire the necessary tools. By combining one or more different sized cookware devices into a single adjustable cookware device, both excess cost and wasted storage space are minimized. This might be particularly useful in environments where space as at a premium, for example in small kitchens, such as those of apartment dwellers.

The present disclosure is generally directed to adjustable cookware devices that are convertible from a flat baking sheet to at least a first sized baking pan. In various example embodiments, the adjustable cookware device includes a base sheet and a plurality of flanges pivotably connected to the base sheet. In various embodiments, the plurality of flanges are adjustable from a first substantially flat position with respect to the base sheet to a second substantially upright position with respect to the base sheet. When in the second substantially upright position, the plurality of flanges can be secured to one another to define a first baking zone. In various embodiments, the first baking zone is similar to the shape of a common baking pan, with the plurality of flanges serving as the baking pan walls and the base sheet serving as the baking pan base. In various embodiments, the base sheet includes more than one set of flanges, each set of flanges corresponding to a different sized baking zone when arranged in the respective second substantially upright position. In various embodiments, the adjustable cookware device has several different operating configurations, depending upon the arrangement and dimensions of the plurality of flanges operably connected to the base sheet.

Referring now to FIG. 1, a flattened example of one adjustable cookware device embodiment is discussed and illustrated. The adjustable cookware device 100 includes a plurality of flanges 104a, 104b, 104c, 104d, 106a, 106b, 106c and 106d which are each adjusted into a position that is substantially flat with respect to base sheet 102. In such a flat configuration, the adjustable cookware device 100 can be used as a cookie sheet or baking pan. It should be appreciated that in various embodiments discussed in more detail below, the base sheet 102 is designed to have a plurality of cutouts where the flanges 104a to 104d and 106a to 106d are to be attached. In one such embodiment, when the flanges 104a to 104d and 106a to 106d are pivoted to a flat position, the base sheet 102 and the flanges 104a to 104d and 106a to 106d combine to define a substantially coplanar surface on which items can be baked. It should be appreciated that the base sheet 102 and the flanges 104a to 104d and 106a to 106d are designed so that when used in the flat configuration as a baking sheet, the thickness is substantially constant throughout the adjustable cookware device 100. Therefore, in various flat-configuration embodiments, assuming even heat application by the oven or other heat source, the heat distribution is consistent across the entire adjustable cookware device 100.

In various embodiments, the adjustable cookware device includes four separate pivotable flanges arranged in a rectangular or square array on the base sheet. In one embodiment (not illustrated), the adjustable cookware device includes only four pivotable flanges. In various embodiments, when the four flanges are pivoted to an upright position with respect to the base sheet, the flanges create four walls defining a rectangular or square baking pan or baking zone. It should be appreciated that, in various embodiments, a cutout portion of the base sheet, from which the four flanges are pivoted upright, provides a peripheral surface surrounding the rectangular baking pan on which additional food items may be baked. As will be discussed later, when the four flanges are pivoted into the upright configuration to define the baking zone, each of the seams are secured and constructed to prevent leakage and uneven baking.

Referring again to FIGS. 1 to 3, in various embodiments, the adjustable cookware device 100 includes eight separate pivotable flanges. As shown in FIG. 1, one such eight-flange embodiment includes two sets of four flanges, each arranged in a rectangular or square array on the base sheet 102. The first or inner set of four flanges 104a, 104b, 104c and 104d are each arranged perpendicularly to one another in a rectangle. The flanges 104a, 104b, 104c and 104d are pivotably connected to base plate 102 and arranged in a flat configuration so that the tops of each of flanges 104a, 104b, 104c and 104d are substantially coplanar with the center portion of base plate 102. Similarly, FIG. 1 illustrates a second or outer set of four flanges 106a, 106b, 106c and 106d, each arranged perpendicularly to one another in the shape of a rectangle. The flanges 106a, 106b, 106c and 106d are each pivotably connected to base plate 102 and arranged in a flat configuration so that the tops of each of flanges 106a, 106b, 106c and 106d are substantially coplanar with the center portion of base plate 102 and the tops of each of flanges 104a, 104b, 104c and 104d.

It should be appreciated that in the illustrated embodiment of FIG. 1, the first or inner set of flanges 104a to 104d have a first width and the second or outer set of flanges 106a to 106d have a second width less than the first width. As discussed in more detail below, due to the flange width differential between the 104 series of flanges and the 106 series of flanges, the resulting first and second baking zones defined when the flanges are configured in an upright position have differing depths (see FIGS. 2 and 3).

Referring now to FIG. 2, one example embodiment of a first upright configuration of the adjustable cookware device 100 discussed in FIG. 1 is illustrated and discussed. In FIG. 2, the flanges 104a, 104b, 104c and 104d have been pivoted from a flat configuration (show in FIG. 1) up to an upright configuration that is substantially perpendicular to the base sheet 102. In various embodiments, base plate 102 includes a plurality of cutout portions 204a, 204b, 204c 204d now visible with the flanges 104a to 104c upright. The cutout portions 204a to 204d are dimensioned such that their depth is roughly equal to the thickness of flanges 104a to 104d. Therefore, when the flanges 104a to 104d are pivoted into a flattened configuration, as discussed above and illustrated in FIG. 1, the flanges 104a to 104d lie flat and substantially coplanar and flush with the top of center portion of base plate 102.

As illustrated in one example embodiment in FIG. 2, within the cutout portions 204a, 204b, 204c and 204d of various embodiments, the base plate 102 includes a plurality of integrated bosses 110a, 110b, 110c, 111a, 111b and 111c. It should be appreciated that, while FIG. 2 only shows two full sides of the integrated bosses in cutouts 204b and 204c, in FIG. 4, additional bosses corresponding to flanges 204a and 204d are disposed in a mirror configuration in mirrored cutouts 204a and 204d respectively. It should be appreciated that in various embodiments, cutout 204b mirrors cutout 204d and cutout 204a mirrors cutout 204c. Similarly, in various embodiments, bosses 110a to 110c in cutout 204c are mirrored in cutout 204a and bosses 111a to 111c in cutout 204b are mirrored in cutout 204d. It should also be appreciated that, by making flanges 104a and 104c identical and interchangeable and flanges 104b and 104d identical and interchangeable, a user need not worry about matching unique components after disassembly and cleaning.

In various embodiments, the integrated bosses 110a, 110b and 110c and 111a, 111b and 111c are configured to interface with matching mating female voids integrated into the bottom side of corresponding flanges 104c and 104b. In the flat configuration illustrated in FIG. 1, the female voids of flange 104c are snap secured with the male bosses 110a, 110b and 110c to keep flange 104c secured in the desired flat position. As discussed in more detail below, in various embodiments both the female voids of the flanges 104a to 104d and the male bosses 110a to 110c and 111a to 111d are constructed with durable silicone. In various alternative embodiments, the female voids and male bosses, as well as the flanges are constructed with rubber or another suitable material discussed in more detail below. It should be appreciated that, when snapped into the flat secure position, the flanges 104a to 104d are held with sufficient force that the heat and expansion experienced by being put into and out of the oven is not sufficient to release the flanges unintentionally. However, in various embodiments, it should be appreciated that the flanges are not too tightly secured such that a user has a difficult time unsnapping the flanges from the bosses to use the pivotable upright embodiment.

End flanges 104a and 104c each include two opposing flap portions 300a, 300d and 300b, 300c respectively. In various embodiments, each flap portion 300a to 300d is integrally connected to one of the end flanges 104a, 104c and constructed to pivot with respect to its respective base end flange when unsnapped from the corresponding bosses. Viewing FIG. 2, it will be appreciated that each flap is enabled to pivot with respect to the end flange in part because its freedom of motion is not inhibited by being pivotably connected to the base plate 102. While the center portion of end flanges 104a and 104c are pivotably connected to the base plate 102, the end flaps 300a to 300d are not. It should be appreciated that in various embodiments, each end flap 300a to 300d includes the definition of at least one female void 121a to 121d respectively.

In various embodiments, the bottom surface of side flange 104b includes boss portions 120a, 120b disposed on opposing ends of the flange 104b. Although not illustrated in FIG. 2, it should be appreciated that flange 104d also includes similar boss portions 120c, 120d on opposing sides of its bottom portion. In various embodiments, the boss portions 120a to 120d are configured to integrate with female voids 121a to 121d respectively. It should be appreciated that the mating of bosses 120a to 120d with female voids 121a to 121d is mechanically similar to the mating of bosses 110a to 110d and 111a to 111d with the corresponding female voids disposed on the bottom surface of the flanges. It should be appreciated that, to keep the seams from leaking during baking, as discussed in more detail below, the bosses 120a to 120d and the voids 121a to 121d in various embodiments are constructed to be slightly larger and more robust to provide more holding force and sturdy snapping than the flat-snap bosses 110a to 110d and 111a to 111d.

To adjust the adjustable cookware device 100 from the flat configuration of FIG. 1 to the first upright configuration of FIG. 2, flanges 104a to 104d are each unsnapped from the respective securing bosses discussed above, and are snapped together with vertical bosses 120a to 120d and corresponding voids 121a to 121d that are integrated into each of the flanges 104a to 104d. In various embodiments, it should be appreciated that, in the upright configuration, the flanges 104a, 104b, 104c and 104d are not perfectly perpendicular to the base plate 102 but are pivoted from a 0 degree angle defined by each flange 104a to 104d with respect to the corresponding cutout portion 204a to 204d of the base plate 102 to an acute angle defined by each flange 104a to 104d with respect to the cutout portion 204a to 204d of the base plate 102. It will be appreciated that making the minor geometrical adjustments to allow such an acute angle (as opposed to a right angle) results in various embodiments in which the baking zone defined by the upright flanges has slightly outward-tapered walls, which may be preferable to cooks and bakers.

It should also be appreciated that, in various embodiments, the flanges 104a, 104b, 104c and 104d are pivoted from a 0 degree angle defined by each flange 104a to 104d with respect to the corresponding cutout portion 204a to 204d of the base plate 102 to an obtuse angle defined by each flange 104a to 104d with respect to the cutout portion 204a to 204d of the base plate 102. It will be appreciated that making the minor geometrical adjustments to allow such an obtuse angle (as opposed to a right or acute angle) results in various embodiments in which the baking zone defined by the upright flanges has slightly inward-tapered walls, which may be preferable to cooks and bakers.

In the embodiment discussed above and illustrated in FIG. 2, the flanges 104a to 104d are pivoted to an upright configuration to define a first baking zone, which has dimensions of: length equal to the length of the side flanges 104b, 104d; width equal to the length of the end flanges 104a, 104c minus the respective end flaps 300a to 300d; and depth equal to the height of each of the flanges 104a to 104d.

Referring now to FIG. 3, an example embodiment of the adjustable cookware device in a second upright configuration is discussed and illustrated. It should be appreciated that the second upright configuration utilizes the second set of four flanges 106a, 106b, 106c and 106d. In the second upright configuration, each of the first four flanges 104a to 104d are pivoted into the flat position and secured using the respective bosses and female voids defined in the outside surface of each of the flanges. In the second upright configuration, the user can convert the adjustable cookware device 100 into a baking zone or pan that is of a different length, width and depth than the baking zone or pan defined in the first upright configuration discussed above and illustrated in FIG. 2.

In various embodiments, flanges 106a to 106d are attached to base plate 102 in a similar fashion as flanges 104a to 104d discussed above. The flanges 106a to 106d in their flattened configuration occupy the cutout portions 206a to 206d of base plate 102, respectively. As seen in FIG. 3 in conjunction with the cutout view of base plate 102 in FIG. 4, raised sections 400a, 400b, 400c and 400d provide points of contact between the flanges 106a to 106d and the base plate. It should be appreciated that, in various embodiments: flange 106a is pivotably connected to the base plate 102 on one end at raised portion 400d and on the other end at raised portion 400a; flange 106b is pivotably connected to the base plate 102 on one end at raised portion 400a and on the other end at raised portion 400b; flange 106c is pivotably connected to base plate 102 on one end at raised portion 400b and on the other end at raised portion 400c; and flange 106d is pivotably connected to base plate 102 on one end at raised portion 400c and on the other end at raised portion 400d. In alternative embodiments, discussed in further detail below, the attachment of flanges 104a to 104d and 106a to 106d are connected to base plate 102 in various different ways.

Similar to the cutout portions 204a to 204d of base plate 102, cutout portions 206a to 206d also include a plurality of bosses or protrusions configured to interface with each of the respective flanges 106a to 106d when in the flattened position. As seen in FIG. 3, the bosses in cutout portions 206b and 206c, which correspond with flanges 106b and 106c respectively, are illustrated. In cutout portion 206b, bosses 112a, 112b and 112c protrude from base plate 102. Flange 106b includes female voids or depressions on its bottom surface that correspond to each of bosses 112a, 112b and 112c. Similarly, in cutout portion 206c, bosses 113a, 113b and 113c protrude from base plate 102. Flange 106c includes female voids or depressions on its bottom surface that correspond to each of bosses 113a, 113b and 113c. Although not illustrated in FIG. 3, flanges 106a and 106d also include a plurality of similar female voids and the respective cutout portions 206a and 206d of base plate 102 include a plurality of matching bosses or protrusions to mate with the voids.

As seen in FIG. 3, in various embodiments, end flanges 106a and 106c each include two opposing end flaps 302a, 302d and 302b, 302c respectively. Similar to the mechanism discussed above with respect to flanges 104a to 104c, the flaps 302a to 302d corresponding to flanges 106a and 106c each include a female void 131a and 131b. It should be appreciated that the illustrated exemplary female voids 131a and 131b defined on the flaps 302a and 302b are sized to mate with corresponding bosses or protrusions 130a and 130b respectively disposed on flange 106b. It should be appreciated that, although not fully illustrated, each of flaps 302c and 302d also include female voids similar to 131a and 131b and flange 106d also includes corresponding bosses or protrusions similar to 130a and 130b.

In the embodiment discussed above and illustrated in FIG. 3, the flanges 106a to 106d are pivoted to an upright configuration to define a second baking zone, which has dimensions of: length equal to the length of the side flanges 106b, 106d; width equal to the length of the end flanges 106a, 106c minus the length of respective end flaps 302a to 302d; and depth equal to the height of each of the flanges 106a to 106d.

It should be appreciated that, when the side flanges and end flanges are each suitably connected to one another in an upright configuration, each seam is liquid tight and sealed to prevent any pre- or post-baking leakage of or seepage ingredients within the baking zone. It should also be appreciated that, the seams along the pivoted edges of each of the flanges are also liquid tight and sealed with respect to the base plate to prevent any pre- or post-baking leakage or seepage of ingredients within the baking zone.

It should be appreciated that, in various embodiments, different adjustable cookware devices can be designed and manufactured to include differing sized flanges and thereby offer to the end user different popular or standardized baking zones useable with one device. For example, in one embodiment, the inner or first flanges are each dimensioned 8 inches long by 1.5 inches wide. After in an upright configuration, this first baking zone would create an 8 inches by 8 inches by 1.5 inches cake pan, which is a typical size that corresponds to many recipes. In another embodiment, in addition to the 8 inch by 8 inch by 1.5 inch inner pan, the outer or second flanges are dimensioned to create a 9 inch by 13 inch by 2 inch shallow cake plan. It should be appreciated that any number of permutations or combinations of flange sizes can be combined into various embodiments of the present disclosure.

In various embodiments, the general dimensions of the flange sizes are standardized to enable interchangeability of flanges between several differently-sized adjustable cookware devices. For example, suppose a user wished to use the 8 inch by 8 inch sized pan discussed above, but rather than having a depth (wall-size) of 1.5 inches, the user wished to have a depth of 3 inches. Due to the interchangeability and standardization of the flanges and base plates, a separate set of flanges of the dimensions 8 inches by 8 inches by 3 inches could be inserted into the base plate. So long as the length of the flanges fits with the corresponding flange-lengths in the base plate, the height of the flanges in the upright configuration can be variable. This standardization provides greater flexibility as to the size and customization of the baking zone. In various embodiments, different sized flanges of a similar length are available separately from the adjustable cookware device to enable the user to create any depth custom baking zone desired. It should be appreciated that, in various embodiments in which the flanges are wider, a secondary securing mechanism can be employed to ensure seal-tight seams between the flanges. In one such embodiment, the secondary securing mechanism is a second set of bosses above the first set of bosses described above.

In various alternative embodiments, the adjustable cookware device is round. In one such embodiment, the base sheet is round, and each of a plurality of flanges are configured to adjust from a flat position to an upright position to define a round, oblong or elliptical baking zone. It should be appreciated that, in various embodiments the baking pan is useable as a pizza sheet, and the baking zone defined by upright-oriented flanges is useable as a pie dish. The baking zone in various circular or oblong embodiments is defined with two semi-circular flanges that pivot upward and connect to one another and the base sheet to form the circular or oblong baking zone. In other embodiments, the circular or oblong baking zone is defined with four flanges configured to each connect to one another and to the base sheet to form the baking zone. It should be appreciated that any number of various embodiments or configurations of shapes and sizes is contemplated herein.

In various embodiments, the adjustable cookware device is configured to include additional flanges to create additional cooking zones. For example, in one embodiment, a baker using the adjustable cookware device in a first configuration to bake brownies could also use the outer periphery of the adjustable cookware device to cook other foods, such as cookies. It should be appreciated that to use multiple areas of the adjustable cookware device simultaneously, the goods must also require similar temperatures and baking durations. In various embodiments, the adjustable cookware device includes one or more bisecting flanges which divide a baking zone into two or more individual baking zones. Such an embodiment allows for baking of multiple similarly-sized food items simultaneously. One example embodiment of such a bisecting flange configuration is if a fifth flange was integrated into the first upright configuration of FIG. 2 extending across top surface 202 from flange 104b to 104d. It should be appreciated that any number and combination of flanges are contemplated for use with the base plates of various embodiments. For example, in one embodiment, one or more diagonal collapsible flanges are configured to bisect the baking zone and create two or more sub-baking zones. In other example embodiments, a series of perpendicular or diagonal patterned internal flanges are configured to create several smaller baking zones to create, for example, a plurality of individual brownies or cakes.

It should be appreciated that, in various embodiments, the flanges are removably connected to the base plate. In other various embodiments, the flanges are not removably coupled to the base plate. In one such embodiment, the flanges are hinged permanently to the base plate. It should also be appreciated that in various embodiments, some flanges are permanently hinged to the base plate whereas other flanges in the same embodiment are removably coupled or hinged to the base plate. Any combination of permanently and removably coupled flanges are contemplated for use in various embodiments.

In various embodiments, the adjustable cookware device is constructed with temperature resistant materials capable of withstanding heat up to at least about 550 degrees Fahrenheit. In other embodiments, the device, with or without post-sale modification can withhold up to about 900 degrees Fahrenheit. In one embodiment, the flanges are constructed with multiple different materials, such as one or more of silicone, plastic, rubber and metal. In various embodiments, the materials used for construction of the base plate of the adjustable cookware device as well as the flanges is a non-stick material, aiding in the removal of baked food items as well as the cleaning of the adjustable cookware device. In various embodiments, the material is dishwasher safe. It should be appreciated that, for purposes of this description, all references to the specific material of the flanges, such as silicone, is not intended to limit the types of materials used for that purpose in various alternative embodiments. The present disclosure also contemplates the use of alternate materials, such as plastic, rubber, synthetics or other appropriate cook-safe surface materials, for use in both the flanges and the base plate. In some embodiments, the flanges include a different material than the base plate.

It should be appreciated that both the non-stick and the pivotable qualities of the flanges and the base plate allow a user to more easily access the finished food item. For example, in various embodiments, when the food item has been completely baked, the user can allow it to cool and then pivot the flanges down from the upright position, making the finished product more easy to cut, serve and display. In various embodiments, the adjustable cookware device is configured to engage with a corresponding support system to be used as an aesthetically pleasing serving tray.

It should be appreciated that in various embodiments, the surface of the adjustable cookware device which contacts the food being baked is a silicone material, and is supported with various metal or otherwise rigid inserts. In one embodiment, the metal or rigid structural insert is completely molded over or encapsulated by the silicone material. For example, in one embodiment, the metal insert or structural rigid member inside the silicone flanges or base plate is a rod configured to support the respective portion of the adjustable cookware device. In another embodiment, the metal insert or structural rigid member is a metal plate. In another embodiment, the metal insert or structural rigid member is a metal mesh plate. In another embodiment, the metal insert or structural rigid member is a bent metal bar. It should be appreciated that various combinations of the different support systems could be used in a single adjustable cookware device embodiment. It should also be appreciated that the metal or rigid insert is configured to help ensure even heat distribution when the adjustable cookware device is placed in the oven or baking environment. In various embodiments, the rigid structural member is molded into the respective silicone member at the time of manufacture.

Referring now to FIGS. 7 to 14, various different embodiments of flanges are discussed and illustrated. It should be appreciated that the structural rigid insert can take various alternative shapes as well as materials. It should be appreciated that any combination of materials, alternative shapes and sizes of flanges can be used in various contemplated embodiments of the disclosure.

Referring specifically to FIGS. 7 and 8, a side view and cross-sectional view of one embodiment of a flange 300 of the present disclosure is illustrated. The structural rigid insert 304 included in the flange 300 of FIG. 7, for example, is a round tube or rod bent, formed or assembled into a continuous loop, roughly following the perimeter of the flange 300. It should be appreciated that in various embodiments, the silicone or other material 302 is molded over the structural rigid insert 304. In various embodiments, the structural rigid insert 304 of FIGS. 7 and 8 is arranged or formed in any suitable shape within the molded over silicone material 302 to provide suitable structural support and integrity to the flange 400. As seen in FIG. 8, the cross-sectional view taken along line VIII-VIII of FIG. 7 is illustrated. The structural rigid insert 304 has a circular cross section.
